如果你厌倦只以「点点」提示(iPhone画面左上角)目前讯号强弱的话,在电话App中,输入「*3001#12345#*」并按下拨号按钮,就会进入Field Test Mode,此时,iPhone左上角的讯号显示图示将会变为数字,范围则从-40到-130,-40显示讯号最好,-130则是表示讯号很差。这个数字永远是负数,要学会如何正确辨识才够实用。 iPhone...
你可以在iPhone上打开电话应用,输入*3001#12345#*,然后按电话拨打键,进入Field Test Mode。它不会打电话,而是会打开Field Test应用。 Field Test Mode以前很有用,因为它可以把蜂窝信号条变成数字测量,但这在现代iOS最新版本的iPhone上是行不通的。 有时看到蜂窝信号用数字表示还是很有用的,这在iOS 13和iOS 14上...

So, in the ios15 field test mode it looks like it is set up for 5G while still serving LTE, 4G,3G, etc, with the Neighbor tower being the main tower for LTE as it is always capturing the signal of the strongest tower. Having said this the formula for RSRQ, I have found, is ...
Field Test Mode is a hidden feature on the iPhone which allows you to see technical details of the device, the most useful of which is the true cell signal strength displayed as a number rather than the traditional signal bars or dots. We’ll show you exactly how to enter Field Test Mod...
Viewing your signal strength in iOS 7, 8, 9, or later comes with another trick to replace the bars with decibel measurements. iPhone models without a physical home button will also support this method. After performing the Field Test Mode by dialing in the code *3001#12345#*, hold your ...
